用adc0809+12864做的一个简单的示波器，可采到1K左右的波形，附带ds1302时间显示程序,Adc0809+12864 to do with a simple oscilloscope, can be taken to around 1K waveform display program with ds1302 time

12864取模及显示原理，附Proteus仿真源文件及keilC驱动程序-12864 modulus and display principle, with Proteus simulation source files and drivers keilC

12864和at89C51相连接显示模块代码，本作中的adc采用的是adc0808.-12864 and at89C51 connected display module code, this made the adc is used adc0808.
